The Downfall of the Mibu Clan
In 1590, during Toyotomi Hideyoshi’s siege of Odawara, Mibu Yoshio, the the lord of Mibu Castle, sided with the Hojo clan along with his brother-in-law, Minagawa Hiroteru. This choice would determine the fate of the Mibu clan.

After the fall of the Mibu clan, Mibu Castle was successively ruled by hereditary daimyo, primarily vassals of Tokugawa Ieyasu. This frequent change of castle lords is a major characteristic of Mibu Castle during the Edo period.
Main Lords of Mibu Castle from 1600 onwards:
